Question

If a dozen of bananas cost ₹ 24, while 10 apples cost ₹ 100, then how many times an apple is costlier than a banana?

• A. Three times
• B. Four times
• C. Five times
• D. They have the same price

Answer 1

The correct option is C

Five times

The cost of 12 bananas = ₹ 24,
So, the cost of one banana =
$\frac{₹24}{12}=₹2$

The cost of 10 apples = ₹ 100,
So, the cost of one apple =
$\frac{₹100}{10}=₹10$

Therefore, the ratio of the cost of an apple to that of a banana = ₹ 10 : ₹ 2 = 5 : 1.

So, an apple is five times costlier than a banana.
